Delhi-NCR Air Pollution: How Poor AQI Can Affect Your Health
Air pollution is a recurring public-health concern in Delhi-NCR, particularly during the cooler months when weather conditions can contribute to the accumulation of pollutants.
The Delhi government’s AQI dashboard reported an Air Quality Index of 224, classified as “Poor”, at 11 am on 23 October 2026. The dashboard identified PM2.5 as the leading pollutant at most reporting stations. Air quality can change throughout the day, so residents should check current readings rather than assume that conditions remain the same.
Delhi AQI
Why is air pollution harmful?
Air pollution contains particles and gases that can affect different parts of the body. Fine particulate matter, including PM2.5, is small enough to penetrate deep into the lungs.
Exposure can cause irritation, coughing, wheezing and breathing discomfort. Air pollution is also associated with increased risks of cardiovascular and respiratory diseases, including heart disease, stroke, chronic obstructive pulmonary disease and lung cancer. The World Health Organization identifies polluted air as a major global public-health threat.

The effects depend on the pollutant, its concentration, the duration of exposure and a person’s health. Children, older adults and people with existing heart or lung conditions can be particularly vulnerable.
How can you reduce exposure on polluted days?
Check the AQI before outdoor activities. Use official air-quality dashboards and forecasts to understand local conditions. Readings may differ between neighbourhoods.
Reduce strenuous outdoor exercise when pollution is high. Consider moving running, cycling or other intense activities indoors, particularly when official advisories recommend limiting exposure.
Use a suitable mask when advised. A well-fitted N95 or equivalent particulate respirator can reduce exposure to airborne particles when worn correctly. Fit matters, and masks do not eliminate all pollution risks.
Improve indoor air where possible. Keep windows closed when outdoor pollution is high, while maintaining appropriate ventilation when conditions improve. If using an air purifier, select one suitable for the room and follow its maintenance instructions.
Avoid adding indoor pollution. Do not smoke indoors, and minimise activities that create smoke or fine particles. Avoid burning waste or leaves.
Should children and older adults take extra care?
Yes. Children’s lungs are still developing, and older adults may be more likely to have underlying health conditions.
Schools, parents and caregivers should follow official advisories on outdoor sports and physical activities. People with asthma or other respiratory conditions should follow their clinician’s treatment plan and keep prescribed medicines available.
Seek urgent medical help if someone develops severe breathing difficulty, chest pain, fainting or other serious symptoms. Do not dismiss significant symptoms as a normal response to pollution.
Can one person solve Delhi’s air pollution problem?
Individual precautions can reduce personal exposure, but lasting improvement requires broader action. Cleaner transport, industrial emissions control, construction-dust management, effective waste handling and coordination across neighbouring regions all matter.
Pollution also varies by source and location, so interventions need reliable monitoring and enforcement.
The bottom line
Poor air quality is not simply a visibility problem. It can affect respiratory and cardiovascular health, particularly among vulnerable groups.
Check the AQI, adjust outdoor activity when necessary and follow official guidance. For current readings and health advice, consult the Delhi AQI dashboard and the World Health Organization’s air-pollution guidance.
![India is facing a complex nutrition challenge, with overweight and obesity increasing while below-normal BMI remains a concern, according to findings from the latest National Family Health Survey, NFHS-6. The findings highlight what researchers and public-health experts describe as a dual burden of malnutrition, where undernutrition and excess weight exist within the same population. A report on the NFHS-6 findings published this week said the decline in below-normal BMI has stalled while overweight and obesity rates continue to rise. ([The Times of India][4]) The development is significant because nutrition problems are no longer limited to one side of the spectrum. Being underweight can be associated with inadequate nutrition and other health challenges, while overweight and obesity are associated with increased risks of several non-communicable diseases. The coexistence of these conditions creates a complicated public-health situation. Changing lifestyles are one factor highlighted in the discussion around rising overweight levels. Increasingly sedentary routines and greater dependence on digital activities can reduce physical activity. At the same time, access to adequate and nutritious food remains uneven across communities. This means India's nutrition challenge cannot be addressed through a single intervention. Public-health strategies need to consider both adequate nutrition and the prevention of unhealthy weight gain. The findings also demonstrate why national health surveys are important. Large-scale surveys help governments and researchers understand how health indicators are changing across populations. For individuals, the figures reinforce the importance of looking beyond weight alone. A person's health is influenced by diet quality, physical activity, sleep, medical conditions and other factors. The dual burden also creates challenges for healthcare systems. Doctors and public-health workers may need to address undernutrition in some populations while simultaneously dealing with increasing rates of overweight and obesity in others. The NFHS-6 findings therefore point towards a more complicated nutrition landscape in India. Instead of treating malnutrition as only a problem of inadequate food, public-health planning increasingly has to account for both nutritional deficiency and excess calorie consumption.](https://xhealth.onextelcommunication.com/wp-content/uploads/2026/09/ChatGPT-Image-Sep-23-2026-06_37_19-PM-450x290.png "India Faces Dual Nutrition Challenge as Overweight and Underweight Persist")
